Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Urbanisation and human activities influence the co‐occurrence of red squirrels Sciurus vulgaris and meso‐carnivores in Berlin, Germany

Wildlife Biology, EarlyView.
Urban expansion is a major driver of habitat fragmentation, shrinking wildlife habitat, and restricting wildlife movements and activity patterns. In this novel environment, species must adapt to the new composition of wildlife communities. For example, red squirrels Sciurus vulgaris are commonly found in urban environments, while their potential ...

Field test of assumptions for using line transect distance sampling on rock ptarmigan

Wildlife Biology, EarlyView.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Parturition timing and the pre‐ and post‐partum behaviour of female moose assessed using animal‐borne video and movement‐based approaches

Wildlife Biology, EarlyView.
Limited information on moose calving behaviour, including parturition timing, cow‐calf interactions, and pre‐ and post‐partum movement patterns hinder our ability to define calving phenology and habitat use. GPS‐collars were deployed on 89 female moose over five years, including eight collars equipped with animal‐borne video and environmental data ...
